Ben Godfrey has not suffered serious ankle ligament damage, revealed Daniel Farke, after Tuesday’s behind-closed-doors 4-1 friendly win against SC Bonner in Germany.

Godfrey has had the all clear following scans on the injury in the first half of Sunday's tour opener against Arminia Bielefeld. Farke feared the worst after the England Under-20 international rolled his ankle, but Godfrey has only suffered bruising rather than a break or ligament damage.

"If I am honest I am unbelievably relieved about Ben," said Farke. "Nothing is broken. All the ligaments and tendons seem to be alright. The scan was pretty good. Just a hard knock but when the swelling goes down I am pretty confident we will have him back soon.

"That was my biggest concern, not small injuries, but bigger injuries when we have Christoph Zimmermann out. I am pleased the diagnosis is not too bad.

"With Louis it doesn't look too good. It is a major muscle strain.

"He will be out for a few weeks. We have to wait how quickly it settles down."

Kenny McLean (leg muscle) and Josip Drmic (hamstring) sat out the second game with minor knocks. Alex Tettey (calf) and Mario Vrancic (calf) face another seven to 10 days out.

Timm Klose did not feature against SC Bonner but returned to training earlier on Tuesday.

"Kenny over-stretched his leg this morning and felt some small pain. Nothing too bad," said Farke. "Josip felt some pain in his hamstring after the Bielefeld game so we took no risks. It is not a problem if a player misses two or three days.

"Timm trained today. He was able to train with us. We just have to wait until he is game fit. Alex will join us in England. Maybe Tuesday, Wednesday next week said the doctor. Mario has missed the first three weeks but we hope he is back next week as well."

Farke was delighted with the impact of Adam Idah and Sam Byram. Idah struck a brace and Byram provided the assist for Onel Hernandez's third goal.

"Adam has a gift for finishing," he said. "His instinct to be in the right position and get across his defenders. There are several other topics maybe in his game we have to improve and he knows this. You know my attitude with the young lads,

"I don't like to praise them too much, but it is great for a striker's confidence.

"A good first game for Sam. We were a bit concerned because he had long travel and some busy days but he handled the load in the morning training and we it was the best way to throw him straight into the water and to be fair he was able to swim.

"A solid performance, really good assist and it was important for him to get the first minutes under his belt."
